i'b all rv/tom it may concern:

Be it known that l, CLYDE M. Lone, a citizen of the United States, and aresident Toledo, in the county of Lucas and State of @hio, have inventeda certain new and useful Prepared Mortar; and l. do hereby.

declare the following to be a full, clear, and exact description of theinvention, such as will enable others, skilled in the art to which itappertains to make and use the same.

My invention relates to prepared mortar to be used in buildings, suchas, in laying of brick, stone and making of stucco; and it has for itsobject to provide a mortar which is exceedingly smooth and very hard anddurable when set and which may be made at an exceedingly low cost andone which requires a remarkably small proportionate amount of hydratedlime.

It also has for its object to provide a prepared mortar which may bekept in dry form and is at all times in condition for use, upon the mereapplication of water sufficient in amount to cause it to become plastic.

it also has for its object to produce an exceedingly smooth mortar whichis very desirable to masons as it is easily handled and, moreover,conforms itself readily to roughened surfaces and makes a close bind ingcontact with such surfaces.

' my invention it use sand containing particles of free iron, iron oxidand iron which is mixed with hydrated lime in proper proportions. Thismakes a mortar that is exceedingly hard when it has set and requiresproportionately but a very small amount of hydrated lime. I find itpreferto form the mixture containing my in vention, by mixing usedniolders sand with. the hydrated lime. The best mixture do by usingdiscarded molders sand, which is blackened and charged with particles ofiron and slag of iron and theroug ly burnt. This sand is rendered. use--less for molding purposes on account of be- Application filed ()ctober30, 1914. Serial No. 869,464.

ing entirely burnt and filled with iron. Because of the continuousworking to which such sand is subjected, it is exceedingly fine andthat, taken with its composition and the powdered hydrated lime whenmixed therewith makes the mortar exceedingly smooth and easily workableand desirable.

lln forming the prepared mortar I use eight parts of the burnt chargedsandto one of hydrated lime, to ten parts of burntor charged sand to oneof lime, which produces a mortar usable where mortar mixed at the timeof using and formed of the sand now used by masons, hydrated lime andwater, requires two parts of such sand to one of hydrated lime to threeparts of sand to one of hydrated lime.

For mortar requiring little adhesive strength and commonly used forfilling and usually made of ten parts of sand to one of hydrated lime, Iuse 16 parts of burnt or charged sand to one of hydrated lime to obtainsubstantially the same results.

The composition just described may be greatly varied in itsproportionate parts and in the substitution of the ingredients whichwill perform the same functions or accomplish the same results in themixture and such modifications of the composition maybe used for manyvaried purposes and still contain the invention.

Havingithus described my invention, what I claim as new and desire tosecure by Letters Patent, is,

A mortar consisting of burnt molders sand charged with particles of ironand slag and hydrated lime.

in testimony whereof, I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
